This isn’t a caption, but it reminds me of the fight between Darwin and Kor-guu in The Sandwalk Adventures by Jay Hosler. Kor-guu the giant purple space beetle challenged Darwin to a fight in which only the fittest survived, and Darwin won because he had kids and Kor-guu did not.
(My dad gets us the best comic books.)

Darwin: ‘And some fell among thorns, and the thorns grew up, and choked it, and it yielded no fruit.
And other fell on good ground, and did yield fruit that sprang up and increased; and brought forth, some thirty, some sixty, and some an hundred.’
